This invention relates to a new and improved metallic frame for Windows,doors, or the like, and of the type to be utilized in buildingconstruction.

It is an object of the invention to provide a frame of this type whichmay be readily mounted in position in the side walls of a building, andadequately weather-proofed and secured against the elements with aminimum amount of labor.

It is a further object to provide .a frame which is rugged inconstruction and yet which utilizes a minimum of material in proportionto tensile strength of the resultant product.

With these and other objects in mind, reference is had to the attachedsheet of drawings, in which a metallic frame is disclosed embodyingcertain modiiications of my invention.

Fig. 1 is a front elevation of a sector of a building having one of myimproved frames in position and partially broken away to show details ofconstruction;

Fig. 2 is a cross-section of the view shown in Fig. 1, taken along thelines 2-2 in that gure and in the direction of the arrows;

Fig. 3 is a perspective of the frame section shown in Fig. 2, andpartially exploded to show the component parts thereof; and

Fig. 4 is .a cross-section through the base of the frame shown in Fig. 1and disclosing certain details thereof.

In the several views, the numeral I0 represents the body of a framewhich, as will be noted, is preferably formed from a continuous strip ofconstant gauge metal which is bent on itself to form a hollow framemember provided with an outwardly extending channel or shoulder portionII, against one wall ofthe interior recess of which rests one end of themetal used to fabricate the said frame, as has been shown at I2.

The remaining edge of the metal used to form the frame has been bent asat I3 to form a supporting bracket for one edge of the frame, andprovides a shoulder against which bricks or other building material I4may abut. Separating said building brick or other material from thesurface of the Casement is a filler I5, which maybe of oakum, mortar,pitch, or other suitable material and which serves the purpose offilling in the space between the frame and the building material I4.'Ihis is sealed in place by means of asphalt, pitch, or other desiredwater-proofing material as at I6. Prior to such step, however, moldingstrip I'I, formed of the same metal as the body of the frame and formedwith depending lugs I8 for cooperating with slots I9 in the frame body,is positioned along the free edge of the frame and provides a furthershoulder against which the pitch or other suitable material may bedriven home to help position oakum or other material I5. I

It will readily be noted that in utilizing the structure hereindescribed, it will be a relatively easy task for the builder to do aeasement job of calking or weather-proofing the building before theweather strip is in place, and at the same time allows a frame to beutilized of measurements slightly in excess of the masonry frame inwhich they are to be supported and still allow the necessary packing andweather-proofing to be accomplished.

It will be noted particularly in Fig. 2 that the molding strip I1 isprovided with a right angle base 26 which is held in position by thetongue I8 cooperating with the groove I9, and that by this expedient themechanic must necessarily align the face of the frame to correlate withthe vertical face of the surrounding building.

Additonal marginal strips 2I can be provided, if desired, by eitherriveting or welding the same to the sides of the frame, and once inposition, they afford ample support and adequate strength for theplacement of windows or other suitable appurtenances.

In Fig. 4 the frame 22 is disclosed, which is, as has heretofore beendescribed, formed of constant gauge material and which is folded onitself to form a hollow structural member of considerable strength andrigidity. Adjacent the surface 22 is a second thickness of the materialfolded back upon itself, and in which have been formed openings 23 inthe nature of circular punched holes or the like. When the frame is inplace against a glass, brick or other building material, such as I4, abinder, or mortar, 24, is positioned therebetween, which will key intothe openings 23 and prevent a sidewise slippage of the same with respectto the face of the building. If desired, a water-proofing compound 25,of pitch', asphalt, or the like, may be utilized as well, and willprevent the entrance of moisture between the mortar .and the frame, withresultant deterioration due to alternate freezing and thawing, and othercauses.

It is obvious that numerous changes in construction and rearrangement ofthe parts might be resorted to Without departing from the spirit of theinvention as dened in the claims.

Having thus described the invention, what is claimed is:

1. A building frame, with an inner opening 66 and an outer wallreceiving channel for insertion in a building Wall, comprising; anintegral body of constant gauge metal folded upon itself for a portionof its length to form substantially horizontal and spaced inner andouter members and further folded near one end to form a substantiallyvertical building material retentive member for bearing against one sideof said wall; a removable building material retentive member for bearingagainst the other side of said wall and means for retaining saidremovable member in position on said horizontal outer member.

2. A building frame, with an inner opening and an outer Wall receivingchannel for insertion in a building wall, comprising; an integral bodyformed from a sheet of constant gauge metal, one edge folded verticallyto form one shoulder of said wall receiving channel; the remainderfolded upon itself substantially throughout its length to formsubstantially horizontal and spaced inner and outer members, said outermember being formed with spaced apertures; a removable wall receivingshoulder formed with spaced lugs for co-operation with said aperturessuch that when assembled said removable shoulder is substantiallyvertical and forms the other shoulder of said wall receiving channel.

3. A frame of the character described having an inner opening and anouter wall receiving channel, comprising an integral body formed ofsheet metal folded vertically near one edge to form one shoulder of awall receiving channel; the remainder of said sheet folded upon itselffor a portion of its length to form substantially horizontal and spacedinner and outer members, said inner member folded inwardly at one pointto form a shoulder and said outer member folded inwardly at said pointto engage said latter shoulder, a removable building material retentivemember to form the other shoulder of said wall receiving chann-el andmeans for maintaining said member in position on said outer horizontalmember.

4. A frame of the character described having an inner opening and anouter wall receiving channel comprising; an integral body formed ofsheet metal folded vertically near one edge to form one shoulder of awall receiving channel, the remainder of said sheet folded upon itselffor a portion of its length to form substantially horizontal and spacedinner and outer members, said inner member folded inwardly at one pointto form a shoulder and said outer member folded inwardly at said pointto engage said latter shoulder, spaced apertures on said outer member, aremovable wall receiving shoulder formed with spaced lugs forco-operation with said apertures such that when assembled, saidremovable shoulder is substantially vertical and forms the othershoulder of said wall receiving channel.
